ROOFING-TONGS.

I Specification of Letters Patent.

Patented Aug. 24, 1915.

Application filed July 11, 1914. Serial No. 350,466.

To all whom it may concern Be it known that 1, MICHAEL D. SoHAL- LER, acitizen of the United States, residing at Durhamville, in the county'ofOneida and State of New York, have invented new and usefulRoofing-Tongs, of which the following is a specification.

' The invention relates to improvements in roofing tongs.

The object of the present invention is to improve the construction ofroofing tongs and to provide a simple, practical and efiicient tool ofstrong, durable, and inexpen sive construction, adapted to enable oneman, without the use of other tools, to do the work which usuallyrequires two men, and equipped with means for clamping the upturnedportions of the roofing sheets and for bending and squeezing the same toform a smooth, water-tight seam.

With these and other objects in view the invention consists intheconstruction and novel combination of parts hereinafter fully described,illustrated in the'accompanying -preferably thinner and lighter than thedrawing, and pointed out in the claims appended hereto, it beingunderstood that various changes in the form, proportion, size and minordetails of construction, within the scope of the claims, may be resortedto without departing from the spirit or sacrificing any of theadvantages of the invention.

In the'drawing, Figure lis an end elevation of roofing tongsconstructedin accordance with this invention and shown open. Fig. 2 is a sideelevation of the same. Fig. 3' is a similar view, partly in section,showing theopposite sideof the tongs. Fig; 4 is an enlarged sectionalview of the lower portion of the tongs, the clamping jawsbeing closed,and the crimping 'or bending jaw being open. Fig. 5 is a similar view,the crimping or bending jaw being closed. Fig. 6 is a detail sectional"view showing the jaws completely open. Fig.7 is a de tail sectional viewon the line 7-7- of Fig.

.1. Fig. 8 is a detail viewof a portion of a seam having a double fold.or look.

Like numerals of reference designate corresponding parts in all thefigures of the drawing.

In the accompanying drawing, in which is illustrated" the preferredembodiment of the invention, the roofing tongs comprise,

clamping or squeezing jaw 1 fixed to the in their construction, a mainrelatively fixed 5 having laterally extending terminals 6" fittedagainst and suitably secured to the outer face of the main relativelyfixed clamping aw 1. The clamping jaw 1,

which consists of a flat plate of suitable material, is equipped alongits lower edge with an adjustable extension section 7 provided withupwardly extending arms 8 having slots 9 extending'downwardly from theupper ends ofthe arms and receiving screws 10 for clamping the lowerextension section" in its adjustment. The lower extension section 7which is preferably of a thickness and length corresponding to the mainrela tively fixed jaw, is adapted to be adjusted toward and from thesame, and it constitutes a gage for regulating the height of the seam. I

The relatively movable jaw 3, which is between transversely disposedarms 18 of the main bar or lever 2 by a bolt 14 or other suitablefastening'device, and its upperjend is connected by a link 15 with onearm of i an L-shaped operating lever 16. The arms 13 consist of' flatplates or pieces spaced apart and rigidly connected with and extendingfrom the 'mainbar-or lever at a point intermediate of the ends thereof.The inner end 17 of-the link 15 is bifurcated and the upper end 18-ofthe lever his reduced to fit within the bifurcated end 17 of the link.to which it is pivoted by a rivet '19'-orother suitable fasteningdevice. outer end of the link is pivoted by a rivet The 20 or othersuitable fastening device in a bifurcation 21 of the operating lever 16.The operating lever 16 is pivoted at its angle in a loop 22 of the mainbar or lever 2 by a pin 23 or other suitable fastening device.

The loop 22 extends longitudinally of the main bar or lever andconstitutes the upper portion of the same. One arm of the L shapedoperating lever 16 extends outwardly from the pivot 23 to the link 15,and the other arm, which extends outwardly from the said pivot 23, isprovided with a suitable grip or handle 24. The handle arm of the lever16 is adapted to be swung upwardly and downwardly to oscillate the lever4 for opening and closing the clamping or squeezing jaws of the roofingtongs. The opening movement of the clamping o-r squeezing jaws 1 and 3is assisted by a spring 25 located in'the space between the main baror'lever 2 and the lever 4, and fixed at its lower end in a slot 26 of ablock or piece 27, which is rigidly secured between the arms ofsupporting portions 13 of the main bar or lever. The spring 25, whichextends from the block or piece 27 to the upper portion of the lever 4,is loosely connected with the same by a link 28.

' The'main relatively fixed jaw 1 is provided at its ends with lugs orears 29 projecting upwardly and inwardly from the upper edge of the saidjaw 1 and having attaching portions 30 suitably secured to the outerface of themain clamping or squeezing jaw, but the lugs or ears may beformed in any other desired manner. The lugs or ears 29 have alinedopenings for the reception of terminal pivot portions 31 of a bending orcrimping jaw 32 consisting of a flat plate or bar located above the jaws1 and 3-and adapted to swing downwardly from the up wardly inclinedelevated position shown in Fig. 6 to the closed position illustrated inFig. 5. The bending or crimping jaw is provided with a central upwardlyor outwardly projecting lug or ear 33, which is connected by spacedtransverse links 34 with the lower end of an upright operating lever 35.The upright operating lever 35 is fulcrumed near its lower end betweenthe outer portions of the arms 13 by a bolt 36 or other suitablefastening device, and its lower arm 37 ,Which is relatively short, isarranged at a slight angle to the upper arm and is pivoted between theouter end of the links 34 by a rivet 38 or other suitable fasteningdevice. The lever 4 extends-through the space between the links 34 andthe inner ends of the latter are arranged at opposite sides oftheprojecting lug or ear 33 and connected with the same by a pin orrivet 39. The upper terminal portion 40 of the upright operating leveris forked and is equipped with a grip or handle 41 extending across thespace between and suitably secured to the sides of the fork.

The roofing tongs are adapted to form either a single or double seam,and in the formation of a seam, the upturned portions or flanges 42 and43' of roofing sheets 44 are gripped between the clamping or squeezingjaws 1 and 3 by manipulating the operating lever 16'. The upper portionof the flange 43 is then folded downwardly by the bending or crimpingjaw 32, which is actuated tween the clamping jaws 1 and 3. This forms asingle lock seam, but a double lock seam 45 may be made by bending overor folding the upper portion of the seam by first manipulating thebending or crimping jaw and then completing the fold or bend with thesqueezing or clamping jaws. In the formation of a double. seam, theseflanges, constituting the seam, will be made of suflicient height toenable two separate bending and" crimping operations to be performed. Inthe performance of the second set of operations, a single seam, such asis shown in Fig. 5, is gripped between the clamping jaws a properdistance below the top of the seam, and the crimping jaw is thenactuated to bend or partially fold the same. The operation is completedby placing the partially bent or folded-seam between the clamping jawsand operating the latter to force the sides of the bendor fold intoclose contact with each other.
